Xperia Z Review

Xperia Z





  • Sony has a history of late upgrades and updates. After a long await Sony after the Xperia T, TX, V, J, etc. which at launch had Ice Cream Sandwich (4.0), recently in 2013 are getting their Jelly Bean Updates.
  • Far behind on the list, Sony with their latest and greatest Xperia line-up have caused stir in the android market. Xperia Z/ZL announced at the CES 2013 were the first and latest FULL HD phones of 2013 to be released. Global release was fast with India getting this phone in the month of March whereas some countries got the Z/ZL now.
  • None the less Sony with these phones have definitely gone up on the list. Still to beat Samsung but, hey it’s right next to it now. Sony has shown to the world that its best is capable and is now ready to face the ever growing competition Amongst the Android.
  • The Xperia Z phone was launched in the month of March in India and is available in Black, White and Purple options.
  • The Xperia Z in this review is the C6603 Black Xperia Z.
  • Specifications:
    • Operating system– Google™ Android™ 4.1 (Jelly Bean)
    • Processor– 1.5 GHz Qualcomm APQ8064+MDM9215M Quad Core
      • Really handy for multitasking and handling phone functionalities. It’s such a powerhouse that till now I haven’t had my screen frozen or hung up to such an extent that I had to reset to the factory settings.
  • GPU– Adreno 320
    • With the latest Processor Xperia Z houses the latest GPU of the start of 2013(Now is the 330). Graphics are outstanding on this phone. Playing games on it is treat.
  • Size– 139x71x7.9 mm
    • Hesitant at first but, after a while the form factor started to grow on me. At first it felt that it might be a little too big but, in the end it turned out fine.
  • Weight– 146 grams
    • Lighter than a feather, obviously in world of phones.
  • SIM card– Micro SIM
  • Main screen
    • Colours 16,777,216 colour TFT

Though the 1080p display with the BE2 technology is all so good to hear but, in actuality the screen lacks in balancing some of the colours (Primarily the whites and blacks), and the side viewing angles could seriously use some improvements. Other than that it’s a treat to watch movies and play games since only during this that the BE2 kicks in and balances the colours.

Now that that’s over, now for some inside scoop from experience. The Xperia Z has everything that you would expect from a Flagship. A classy good Camera, power house and a full on entertainment house. With the power of Google at its disposal, Sony doesn’t disappoint. Sony, gives away this phone with its own sweet apps such as Walkman, Movies, Album, Sony Select, Car Mode, Scoialife, etc.

In addition to that there are the Sony entertainment services, here in India Sony is offering its Sony LIV and Jive services for free for 6 months of purchase. It’s a perfect combo if you’re a Vodafone user since they too are offering an enticing 3G data plan, 8 GB of data for each of the coming two months of purchase(Well for 2 months of placing that sim into the phone).

Call quality is great on the Xperia Z. Some have complained about the call quality on the Xperia Z but, on mine the other end has really appreciated the quality and clarity of sound received.

Battery life, is okay. You heard it right, I said “Okay”, with such a powerhouse packing so many great features you would expect that the company would place in a great battery to power the beast. But, unfortunately the phone’s battery is just, “sufficient”!

Apps to take note of:

Socialife: Takes all the feed from all the social sites and sources such as Facebook, Twitter, etc. and combine in a well arranged manner to present it on one single app. Helps to keep track of all the updates that matter to you without opening many apps at once.

Walkman: Shakes your world with Clear Audio+ functionality and if you’re not happy with that you always have the option of getting back to changing the audio settings to your desire.

Album: Neatly arranges you’re photographs and places them on various geotagging animations.

MOVIES: Hall of entertainment is what I like to call it. It can play almost all formats of videos and totally has the best way presenting you’re collection that I have ever seen in any smartphone.

Performance can be seen below:

Some of the shots:














Performance wise the Xperia Z doesn’t disappoint, consistent scores in the geekbench application should confirm that for you.

I would like to conclude by simply saying that I give this Smartphone a BIGGGGGG THUMBS UP! If you’re thinking of making it your daily driver than without a doubt buy it, for every bit of penny spent on it, is totally worth the services and the power you get from this phone.


Let there be publicly available telescope!

The Campaign for a nubile telescope.

There have been many applications and books(even interactive ones) that have given us knowledge about our universe, the endless space but, they are unable to show us how it actually looks and feels like.
    Now, a campaign that was initiated a while back has successfully accumulated enough pledges for the Planetary Resource company(whose main aim is to dig for resources in asteroids) to build their telescope which will be available publicly.
        This would allow the common man to have a little closer look at space atleast beyond any book or any application. From a 5th grader to PhD holder to NASA scientists will be able to reap the benefits of this endeavor.
       This will also allow us to look for dangerous asteroids and also for the asteroids that can be used as resource satellite. Another use is the chance of finding alien worlds.
     A step closer to space.

Siri, pays attention to the little things that matter!

Siri, may not be on par with Google now at present but, it makes up in the little things that may seem trivial but, are really needed for a good and sound life.

Latest news in the siri front show that siri can link up to the National Suicide Prevention lifeline. Siri, could previously fund the sites offering counselling but, now everything is a call away.
Makes life easy!

WWDC 2013 keynote roundup!

WWDC 2013, REALLY kicked of with some boring intro but, as it slowly progressed it became a mesmerising!

WWDC 2013 gave us a literally new iOS for the iPhone namely the iOS 7……




The iOS 7 Will be available of iPhone 4 and above, iPad 2 and above (includes mini) and 5th gen iPods touches.

Though iOS was certainly the major announcement that everyone was looking forward too, Apple didn’t disappoint its pro users…..

Yes, a fully revamped new MAC PRO.
A machine which truly can’t be judged by its look. Go through the specs on the Apple website and you’ll be amazed by the shear power depicted by the spec sheet.

The above too were the top announcements of the keynote, of which iOS was even said to had an standing ovation by the crowd that went there.

The other major but, slightly something of the sidelines according to me was the new MAX OS X Mavericks…..

Also, the new and improved MacBook Airs took the stage as well. With the new 4th gen Intel processors, their battery loves have been seriously increased.

All the above upgrades and hardware are said to reach the common man this fall. Though Airs, will ship today itself.
That was all folks a total wrap up of the announcements of this year’s WWDC.

My little views on Gas Turbines!


The characteristic features that comes to the mind when one speaks of the gas turbines are the compression and the heat addition (Combustion) process.
The gas turbines perhaps represents the most satisfactory way of producing large amount of power in a self-contained and compact unit.
The conjuncture of the gas turbines and the petrol engines may be possible in the future.
 However, in smaller gas turbines the inefficiencies in compressions and expansions are great. So, to overcome this there is a need of using a heat exchanger.
 To make it economical, a compact effective heat exchanger must be used in the gas turbine cycle.
 When compared to the Steam Turbines, the Gas Turbines have a modest   20-30% thermal efficiency. The latter has about 38-40% thermal efficiency.
The applications of the Gas Turbines are in the fields of:
1. Aviation                             2. Power generation
3. Oil and Gas industries         4. Marine Propulsion
A Gas Turbine is a self-contained, light weight not requiring any cooling water and generally fit in the overall structure. Thus is used in the aviation and marine fields.
     For the power generation field, it is used because of the fact that it doesn’t need any cooling water. Its sheer simplicity together with the needs for a quick setup and quick start also adds up as the reasons for being used in this field.
In the oil and gas industries, it is used because of the cheaper supply of fuel and low installation costs.
 The following are the limitations of the Gas Turbines:
  1. .    It’s not self-starting.
  2. .       Low efficiencies at part loads.
  3. .       Non-reversibility.
  4. .       High rotor speeds.
  5. .       Overall efficiency is low.
Classifications of Gas Turbines:
The Gas Turbines are mainly classified into the following types:
        1.   Constant pressure combustion Gas Turbines :
             a.   Open Cycle constant pressure gas turbine.
             b.   Closed Cycle constant pressure gas turbine.
        2.       Constant Volume combustion Gas Turbines.


Earlier much heed was paid to the open cycle plants due to the availability of cheap oils and natural gas. But, now as the prices of the oil hike up, there’s a need for the closed cycle plant once again.

Slimmer 13″ Retina MacBook Pro, Dual Mic MacBook Air Expected at WWDC – Mac Rumors

KGI Securities analyst Ming-Chi Kuo, who has proven to have relatively reliable information over the past several years, released a new research note last week stating that this year’s WWDC will see the coming of an updated 13″ retina models with the latest Intel chipsets and a better isight camera. Also, the airs too are said to receive an update. Then there’s the news that the non retina models of the MacBook pros won’t be receiving any updates.

What baffles me is that there nothing mentioned about the 15″ Retina models and also, that they don’t plan on updating the non retina models of the MacBook pros.

What are thoughts on this people?

Crazy as always….Apple!

Apple’s iPhone sales reportedly up 400% in India thanks to aggressive pricing strategies

Apple’s strategy has really worked wonders in India! With sales moving at about 400% one can now start imagining a time when everyone in India would have a iPhone in there pockets. But, even with this development Apple still faces a lot of competition from Samsung and Nokia in India, as these companies still have the upper hand here.
For me, honestly being an Apple iPhone 5 user and a fan of Apple would love to see that day.
  What do you guys and gals think?
